Structural Damage Detection Using Artificial Neural Networks and Wavelet Transform Arthur Shi, Xiao-Hua Yu — With the ever-increasing demand for the safety and functionality of civil infrastructures, structure health monitoring (SHM) has now become more and more important. Finally, the forecasting per-formance of WNN model was compared with the ANN and AR models. For, Wavelet Image compression, Two types of decomposition methods. Kulkarni2 1,2 E & TC Department, G. We are already familiar with other signal processing tools like.
